Description

Technical Field

[0001] The utility model relates to the technical field of rail locking, and more particularly to a rail locking device. Background Art

[0002] During the operation of some rail equipment, the rails provide support and guidance for the operation of the equipment. When the equipment stops running, in order to ensure the stability of the equipment during operation, it is necessary to use a rail locking device to lock and fix the equipment to the rails, so that the equipment can stay stably on the rails during operation, thereby improving operational stability.

[0003] Existing rail locking devices mainly achieve locking and fixing between the equipment and the rails by clamping on both sides. Their locking and limiting effect is poor. When locking and fixing, they can only achieve pressure limiting on one side of the rail, thereby affecting the stability of the equipment when locked on the rail. For example, a windproof and anti-tilt crane provided in the Chinese patent document with authorization announcement number CN205687424U is a type of rail-running equipment. When it stops on the rail, it only uses a rail clamping device to achieve locking and fixing of the equipment on the rail, and the fixing effect is poor. Utility Model Content
